Metzger 58020709 Track Control Arm – Precision Suspension Engineering

The Metzger 58020709 Track Control Arm is a high‑performance suspension component engineered for the BMW 5, 6, and 7 series, including the M5. Designed to replace or upgrade the original factory arm, it delivers superior handling, durability, and ride comfort.

Key Features & Technical Highlights

• Material Excellence: Constructed from high‑strength alloy steel, the arm undergoes rigorous heat treatment to achieve a balance of stiffness and fatigue resistance. This ensures long life even under aggressive driving conditions.
• Precision Machining: Each component is CNC‑machined to exact tolerances, guaranteeing a perfect fit with the vehicle’s suspension geometry. The result is minimal play and consistent wheel alignment.
• Optimized Geometry: The arm’s linkage angles are calibrated for BMW’s rear suspension architecture, providing optimal camber control and reducing tire wear.
• Corrosion Protection: A multi‑layer coating system protects against rust and environmental degradation, extending service life in all climates.
• Compatibility: Fully compatible with the BMW 5 Series (E60/E61), 6 Series (F06/F07), 7 Series (F01/F02), and M5 models. The part number 58020709 is recognized across multiple languages, ensuring easy identification worldwide.
• Installation Simplicity: Designed with the same mounting points as the OEM arm, it can be swapped in without additional modifications or custom tooling.

Performance Benefits

The Metzger track control arm enhances vehicle dynamics in several measurable ways:

• Improved Handling: By maintaining precise wheel alignment during cornering, the arm reduces understeer and improves steering responsiveness.
• Reduced Tire Wear: Consistent camber angles help distribute tire load evenly, extending tread life.
• Enhanced Ride Comfort: The controlled suspension movement absorbs road irregularities more effectively, delivering a smoother ride.
• Increased Safety: Reliable suspension geometry contributes to better braking performance and vehicle stability during emergency maneuvers.

Installation Overview

While the Metzger arm is engineered for straightforward replacement, a step‑by‑step guide ensures optimal results:

1. Preparation: Secure the vehicle on a lift and remove the rear wheels. Drain the suspension fluid if required.
2. Removal of OEM Arm: Loosen the mounting bolts using an impact wrench, then detach the arm from the subframe and control rod.
3. Installation of Metzger Arm: Align the new arm with the existing mounting points. Tighten bolts to the manufacturer’s torque specifications (typically 80 Nm for the main bolt).
4. Reassembly: Reconnect the control rod, reattach wheels, and refill suspension fluid if necessary.
5. Alignment Check: Perform a wheel alignment to confirm that camber, caster, and toe settings are within factory specifications.

Maintenance & Longevity Tips

• Regularly inspect the mounting bolts for tightness; torque them every 10,000 km or as recommended by BMW service schedules.
• Keep the arm free from debris and apply a light coat of anti‑rust spray if operating in coastal or high‑humidity areas.
• Monitor suspension performance during routine drives; any unusual noises or handling changes should prompt inspection.
